0x00F
SPI register
initialization
At the reset cycle the content of this EEPROM
address range is copied to the SPI accessible
volatile memory and will be used during normal
operation.
0x010 –
0x01F
Sensor calibration data
Do not access this address range. Any modification
will result in device malfunction!
0x020

Unique ID
Every device of a production lot has a unique 32-bit
identification number. It can be used for
traceability
purposes. The production lot can be identified by the
date code on every device.
Write access to the ID is prevented.
